'Flexible' is the opposite because it describes something that can bend, adapt, or change form in response to forces, making it receptive to influence or passage. 'Resistant' is similar to impervious, not opposite. 'Solid' and 'Not responsive' are synonyms or related concepts, not antonyms.

Impiety means lack of reverence or proper respect, especially toward religion or sacred things. Its opposite is 'Piety', which means reverence, devotion, and dutifulness in religious observance.

'Spontaneous' and 'Impulsive' are similar to impetuous. 'Momentum' is unrelated physics term. 'Staggering' describes movement, not decision-making style.

'Done spontaneously', 'Unprepared', 'Off-the-cuff', and 'Extemporized' all describe impromptu itself or similar concepts, not its opposite.
